Abstract
A shockwave impulse disruptor system for use in an underwater firearm. The system includes a barrel having a bore, a muzzle, and at least one barrel port. A housing is external to the bore and defines at least a first gas expansion chamber. The expansion chamber is in fluid communication with the barrel port and has at least one exhaust port. The barrel bore and expansion chamber are flooded when underwater. Propellant gases that push a projectile through the bore are vented through the barrel port to force water from the expansion chamber through the exhaust port and to vent propellant gases. This delays the release of gases to surrounding water and reduces the amount of gas expelled through the muzzle.

A shockwave impulse disruptor system for use in an underwater firearm, comprising:
- a barrel having an axial length, a bore, a muzzle at a forward end, and at least one barrel port positioned aft of an axial length midpoint of the bore;
- and
- a housing external to the bore defining at least a first gas expansion chamber, the expansion chamber being in fluid communication with the barrel port and having at least one exhaust port positioned forward of the axial length midpoint of the bore, the barrel bore and expansion chamber being flooded when underwater,
- wherein, propellant gases that push a projectile through the bore are vented through the barrel port to force water from the expansion chamber through the exhaust port and to vent propellant gases, delaying the release of gases released to surrounding water and reducing the amount of gas expelled through the muzzle.
